Clutch Pressure Control Solenoid Valve A Malfunction
What it means
This is a Honda- and Acura-specific code; the same number can mean something different on other makes. The transmission computer detected a fault in clutch pressure control solenoid valve A, a linear solenoid that regulates clutch apply pressure inside the automatic transmission. It can cause harsh shifts or slipping, and the transmission may go into a fail-safe mode.
Models covered: Honda and Acura models with 5-speed automatic transmission, mainly around 2003–2010 (e.g. Accord, Odyssey, Pilot).

Symptoms4
- Check engine light on, and the D indicator may blink on some models.
- Harsh or delayed shifts.
- Slipping, with engine RPM rising without more speed.
- Transmission stuck in one gear (fail-safe) in some cases.
Possible causes6
- Low, old or non-Honda-spec transmission fluid.
- Failed or dirty pressure control solenoid A.
- Wiring or connector fault at the solenoid.
- Dirty or worn valve body.
- Internal clutch wear causing slip.
- Transmission computer fault (rare).
How to diagnose5
- Check transmission fluid level, color and smell using the method in the manufacturer manual.
- Read all transmission codes and solenoid data with a Honda-capable scan tool.
- Check solenoid resistance, wiring and connector against the manufacturer specification.
- Run the solenoid test with the scan tool if available.
- If the circuit is good and symptoms remain, have transmission pressures checked at a specialist.
How to fix5
- Change the transmission fluid with the genuine Honda fluid specified for the car.
- Repair the damaged wiring or connector.
- Replace the pressure control solenoid or its assembly.
- Repair the valve body or transmission if internal damage is found.
- Clear the code, run any relearn procedure the model requires, then test shifting.
Repair cost
In Saudi riyals; the highlighted part is the expected range for this fault.
In the Saudi market: SAR 250–5,000 (≈ USD 67–1,330)
Our prices come from the Saudi market, converted at a fixed rate (SAR 3.75 per USD). Prices in your country may differ a lot, so we show the cost level.
Repairs start with a fluid change or a connector fix, rise for a solenoid, and reach the top of the range if the transmission needs internal repair.
Prices are rough estimates for common cars at independent workshops and vary with the car and the source of the part.

Frequently asked questions
Can a fluid change fix P1768?
Sometimes, if the fluid was old or the wrong type. Use the genuine Honda fluid specified for the car, and if the code returns, check the solenoid and its circuit.
Will driving with P1768 hurt the transmission?
It can. Slipping and harsh shifts heat and wear the clutches faster, so drive gently and have it checked soon.
